The all-new SM5 helmet is the result of more than five years of intensive study, development, and testing. We scrutinized every possible aspect to engineer a helmet that is safe and thoughtfully designed to deliver optimal protection and comfort. This lightweight helmet features a thermo-injected shell incorporating a special polymer blend enhanced by varying degrees of thickness that is engineered to deliver the optimal combination of impact protection and light weight, while the five-density EPS liner ensures the correct density in the correct area for enhanced impact absorption.

Regarding the fabric type, the helmet is made of multi-origin materials with the shell and soft EPS foam coupling to prevent damage to the collarbone in the event of a crash. The emergency release system and removable cheek pads permit the safe and easy removal of the cheek pads while the helmet is still on, while the 3D contoured foam ensures rider comfort. The removable comfort liner is treated with Silverplus fabrics for excellent moisture wicking, effectively drawing perspiration away from the skin.

The soft textile chin strap is 26mm wide, which is wider than certification requirements for optimal safety and rider comfort. Other key design features include an engineered raised area with padding to effectively reduce the forces transmitted to the collarbone and a patented visor release system that ensures the visor is released with the correct pre-determined amount of force, irrespective of the angle of impact.

This helmet, made in the USA, is the result of meticulous attention to detail and a commitment to providing the best possible protection and comfort for riders. The thermo-injected shell, with its special polymer blend and varying thickness, delivers the optimal balance of impact protection and lightweight design. The five-density EPS liner further enhances impact absorption by ensuring the correct density in the correct areas.

The emergency release system and removable cheek pads allow for safe and easy helmet removal, while the 3D contoured foam and Silverplus-treated comfort liner ensure rider comfort and effective moisture management. The wider-than-standard chin strap further contributes to the overall safety and comfort of the helmet. With its innovative features and thoughtful design, the SM5 helmet sets a new standard in motorcycle helmet technology, providing riders with the peace of mind and protection they deserve.
